TREE SURGERY DEFINITIONS

1st Call Trees Limited in Farnham offers crown thinning and reduction services at reasonable prices. We can trim trees to a safe and suitable height so that they won’t cause obstruction in any way.
Sectional dismantle/removal
Sectional dismantling is a way of removing a tree when it is not feasible to fell the entire tree. When dismantling a tree, arborists use either climbing equipment or an elevated working platform. They cut down sections of the tree until it has been completely removed barring the stump.
Crown thinning
Crown thinning is the removal of a portion of smaller/tertiary branches, usually at the outer crown, to produce a uniform density of foliage around an evenly spaced branch structure. It is usually confined to broad-leaved species. Crown thinning does not alter the overall size or shape of the tree. Material should be removed systematically throughout the tree, should not exceed the stated percentage and not more than 30% overall.
Common reasons for crown thinning are:
To allow more light to pass through the tree
Reduce wind resistance
Reduce weight
A once-only operation on species that are known to produce large amounts of epicormic growth
Crown lift

Crown lifting is the removal of the lowest branches and/or preparing of lower branches for future removal. Crown lifting on older, mature trees should be avoided or restricted to secondary branches or shortening of primary branches rather than the whole removal.

Coppicing
The cutting down of a tree within 300 mm (12 in.) of the ground at regular intervals, traditionally applied to certain species such as Hazel and Sweet Chestnut to provide stakes, etc. For more information on our services, give us a call today.
Pollarding
It is the initial removal of the top of a young tree at a prescribed height to encourage multi-stem branching from that point, traditionally for fodder, firewood or poles. Once started, it should be repeated on a cyclical basis always retaining the initial pollard point or bolling as it becomes known.

Crown Reduction

Crown reduction may be used to reduce mechanical stress on individual branches or the whole tree, to make the tree more suited to its immediate environment or to reduce the effects of shading and light loss. Crown reduction cuts should be as small as possible and in general not exceed 100 mm diameter unless there is an overriding need to do so. Reductions should be specified by actual measurements, where possible, and reflect the finished result, but may also refer to lengths of parts to be removed to aid clarity, e.g. ‘crown reduce in height by 2.0 m and lateral spread by 1.0 m, all round, to finished crown dimensions of 18 m in height by 11 m in spread (all measurements approximate.)’. Not all species are suitable for this treatment, and crown reduction should not be confused with ‘topping’, an indiscriminate and harmful treatment.

FELLING

Felling is the process of downing individual trees either as a whole, or with the top dismantled the pole is then felled again as a whole.
